Window frame and sash



NrTEn STATES WINDOW FRAME AND SASH.

SPECIFICATION forming part of Letters Patent N0. 348,526, dated August 31, 1886.

Application filed April 10, 1885.

To all whmn it may concern:

Be it known that I, ALFRED It. Lone- SHORE, of Hazleton, in the county of Luzerne and State of Pennsylvania, have invented a new and useful Improvement in \Vindow Frames and Sashes, of which the following is a specification, reference being had to the annexed drawings, forming a part hereof, in which- Figure l is a front elevation of a window constructed according to my improvement, and Fig. 2 is an enlarged vertical transverse section.

Similar letters of reference indicate like parts in both the figures of the drawings.

The object of my invention is to provide efficient means for preventing the entrance of wind, snow, rain, or dust above and below the upper and lower rails of the sash and between the meeting-rails.

My invention consists in providing at the joints of the sashes, between the sashes themselves and between the sashes and windowcasing,tongues and grooves of approximately semi-elliptical section, which are adapted to each other and arranged to form tight joints when the window is closed.

The window-frame A is made in the usual form, except that the head of the frame is provided with a groove, (1, of approximately semi-elliptical section, and the window-stool 13 is formed with a similar groove, 1), near its outer edge, with its outer wall more inclined than its inner wall, and terminating in a tongue, c, also of approximately semi-elliptical section. The lower rail, (1, of thelower sash, (I, is rabbeted and provided with a tongue, 0, and groove f, which are complementary to the groove 1) and the tongue 0 of the windowstool 13, the tongue 0 of the sashrail (1 being adapted to lit into the groove 1) in the window-stool, and the groovefin the rail (1 being adapted to receive the tongue 0 of the window-stool when the lower sash, G, is closed. The meeting-rail D of the sash (l is provided with a tongue, 0, and with a groove, f, like those described in connection with the lower rail, 0, and the meetingrail E of the upper sash, F, is provided with a tongue, 0, and groove 1), which are com- (No modeL} plementary to the tongue 0 and groove f of the meeting-rail D, so that the tongue of one meeting-rail fits into the groove of the other, forming a dust and air tightjoint. The top rail, G, of the upper sash, F, is provided along its upper surface, at the middle of its width,with a semi-elliptical tongue, g, adapted to [it the groove a in the head of the windowcasing, and form an effectual stop against the entrance of wind or dust at the top of the window when the upper sash is closed. The contiguous faces of the tongues c e and c c are inclined, so that when the sashes are closed the lower sash, O,will be drawn against the window-stool B, and the meeting-rails D E will be drawn toward each other, forming a tight joint between the sashes, and also drawing the sashes against the window-stops, so as to effectually prevent any rattling of the window. The tongue and groove forming ajoint between the lower rail, (1, and the window-stool B are elevated sufficiently above the bottom of the window frame or sill II to prevent them from being reached by rain or sleet, thus avoiding the necessity of ever being obliged to free the tongues or grooves from ice or snow.

I am aware that an English patent has been granted for centrally-pivoted sashes, which, when closed, interlock with their bearings above and below. I am also aware that in an English patent vertically-moving sashes have been provided with interlocking or engaging tongues and grooves. These features, broadly, I do not seek to cover in this application.

I deem it important that the stool B rests upon the lower sill, II, of the frame, and that it provides a very considerable bearing-face, as seen at I), for the vertical cut-away portion of the lower rail of the lower sash. This bearing extends below the plane of the engaging parts I) e and c f, and forms an efficient weather protection. The upper rail of the upper sash also interlocks by the parts a g with the upper portion of the frame.

\Vhat I claim as new is- The combination, with the stool B, having groove 7) and tongue 0, arranged in relation to the sill H to provide a vertical bearing-face, b, and the upper frame having upon the rail G, to engage the groove a, all groove a, of the sashes O F, having their adarranged for joint operation as set forth. jacent rails D E tongued and grooved to interloek, as shown, and the lower mil having ALFRED LONGSHORE 5 a tongue and groove, 0 f, to correspond with \Vitnesses:

the parts I) 0, respectively, a bearing-face to O. \V. KLINE,

eorres )ond with the face I) and a ton ue. JACOB GRIMEWALT.
